Radiator Alphacool NexXxoS XT45 Copper Steel Black 322x280x49mm

The Alphacool NexXxoS XT45 Copper Steel Black 322x280x49mm radiator is a high-performance cooling component engineered for liquid-cooled PC systems. Constructed with a copper core and steel elements, this slim-profile radiator combines thermal conductivity and structural durability while maintaining a black finish that integrates with diverse build aesthetics. With overall dimensions of 322 mm × 280 mm × 49 mm, it is suited to installations where compact height and efficient heat dissipation are required.

Advantages

The copper core ensures efficient heat transfer from coolant to the radiator fins, while steel components provide mechanical strength and long-term stability. The 45 mm fin thickness and optimized internal flow paths increase cooling surface area without excessively increasing pressure drop. The black finish reduces visible reflections and provides a neutral appearance that matches most system components. The radiator’s dimensions and port locations are designed for compatibility with common fan and chassis mounting patterns.

Suitable for

• Custom liquid cooling loops in desktop gaming PCs
• Workstations requiring sustained thermal performance under load
• Compact or mid-tower builds where radiator height must be limited
• Systems using 120 mm or 140 mm fan configurations compatible with the radiator’s mounting pattern

Key specifications

• Material: copper core with steel structural parts
• Finish: black
• External dimensions: approximately 322 mm (width) × 280 mm (depth) × 49 mm (height)
• Fin thickness: 45 mm fin stack profile
• Mounting: standard fan mount spacing compatible with common 120 mm / 140 mm fan arrangements
• Flow design: optimized internal channels for balanced coolant distribution

How to use

Mount the radiator in a location that supports its dimensions and fan configuration, securing it to the case or bracket with appropriate screws. Attach matching fans to the radiator’s exterior surfaces according to desired airflow direction and ensure correct sealing of inlet and outlet ports when connecting tubing. Fill the loop with compatible coolant and perform a leak test at low pump speed prior to normal operation. Monitor system temperatures after installation to confirm expected thermal performance.

Usage recommendations

Use corrosion-inhibiting coolant suitable for mixed-metal radiators when combining copper and steel components. Regularly inspect fittings and tubing for wear and perform coolant changes per manufacturer guidance to maintain peak heat transfer and prevent buildup. Ensure fans used deliver appropriate airflow for the chosen fan configuration to achieve optimal cooling results.
